Wave vs. KwikVoice — same core job, no account required.
Wave is great — if you don't mind creating an account and having your client data live on someone else's server. KwikVoice does the same core job (professional invoices, fast) with nothing to sign up for and nothing stored anywhere but your own browser.

| Recurring billing | Not yet | Yes |
| Multi-currency | Yes | Yes |
| Tax ID field (VAT, IČO, EIN) | Yes — one flexible field, built in | Manual |
Every invoice you create has your client's name, address, and what you charged them. Most free tools — Wave included — process and store that on their servers, tied to an account you had to create just to make one invoice.
KwikVoice runs entirely in your browser. Nothing you type is ever uploaded anywhere. When you close the tab, it's gone — which is either exactly what you want, or a good reason to download your PDF before you do.
To be fair to Wave — it's a genuinely solid free tool, and if you need recurring billing, expense tracking, or you're fine with an account, it does more than KwikVoice. KwikVoice is built for a narrower job: you need one invoice out the door right now, and you don't want friction to get there.
Yes, 100% free, no account, no paid tier.
No — everything happens in your browser. Nothing is uploaded to a server.
If you want to create a single professional invoice fast without creating an account, yes. If you need recurring billing or expense tracking, Wave currently offers more.
Yes — there's a flexible Business/Tax ID field on both your side and your client's side that accepts IČO, VAT, EIN, or any tax identifier you need.
